Use slider zero and button zero on the basic tab for the camera exposure. These values are automatically stored as "DB/Slider 0" and "DB/Button 0" and if your robot reads those network table variables, it gets the slider values.

Within your camera loop, in the enabled case, the code already updates the image size. Similarly, you can update the exposure by reading the button and slider and calling the Set Exposure subVI. It internally checks against current value and only modifies the camera on change.

4. Add a separate Case statement inside the While Loop
5. Wire the same output that feeds the Sample Boolean 1 output to the Case
6. Copy the Camera Set Expos into the Case True case.
7. Wire the Set Expos to the pink camera ref that comes in the left of the While Loop
8. Change the Set Expose input constant to "Hold current"

Once you've put the new code onto the roboRIO, go to the Dashboard Basic tab and press DB/Button 1 to make the camera Hold Current exposure setting.
This would only work once and assumes that the original Set Expos is still set to "Auto".
Once set to Hold current exposure, then if you push the button a second time you won't se any change.
To get it to change again you'd need to add another Set Expos to take it back to "Auto" long enough for the camera to adjust the exposure again, then you could Hold Current again.

Thank you guys for your AMAZING answers!
One last thing, the set Expos sub-vi input is in precentage values and when we put 0 precent it's really dark and when we put any other number it's normal(1,10,50,0.5)... any ideas what is the range?
